Polyphase Energy Metering IC
with Pulse Output
ADE7752/ADE7752A
FEATURES
High accuracy, supports 50 Hz/60 Hz IEC62053-2x
Less than 0.1% error over a dynamic range of 500 to 1
Compatible with 3-phase/3-wire delta and 3-phase/4-wire
Wye configurations
The ADE7752 supplies average real power on frequency
outputs F1 and F2
High frequency output CF is intended for calibration and
supplies instantaneous real power
Logic output REVP indicates a potential miswiring or
negative power for each phase
Direct drive for electromechanical counters and 2-phase
stepper motors (F1 and F2)
Proprietary ADCs and DSP provide high accuracy over large
variations in environmental conditions and time
On-chip power supply monitoring
On-chip creep protection (no load threshold)
On-chip reference 2.4 V ±8% (20 ppm/°C typical) with
external overdrive capability
Single 5 V supply, low power …
